PURPOSE:To detect an overflow of water from a water storing part and a water leakage error by a method wherein in case that there is no variation in pressure value in an increasing direction from a pressure sensing stage, a control means for terminating operation of the hot water feeder is provided. CONSTITUTION:A degree of increasing of water level is calculated during a supplying of set value by a controlling means 13 and the set value water supplying operation is continued while measuring a time period reaching up to a predetermined degree of increase. When the time exceeds a predetermined time, the operation is stopped. In general, the set value water supplying operation is completed when the pressure shows the value of PX+PA and if there is an overflow of the flow storing par 1 at the elapse time (t1), the pressure increasing is not generated, and even if the specified period of time elapses, no increasing of pressure and so an error is detected by a pressure sensor 8 at a point of the specified time (t2) and this signal is discriminated by the controlling means 13 and the operation of the hot water supplying source 10 and the pump 6 are stopped. |
